This Boyle-Mariotte Law Calculator can estimate the pressure or the volume change of gas if you provide 3 out of the 4 variables in the Boyle-Mariotte’s equation where the temperature (t) is constant. You can get the formulas used below the form.
How does this Boyle-Mariotte Law Calculator work?
This tool can be used to compute any change in pressure or volume of gas by taking account of the Boyle-Mariotte’s Law which states that when mass and temperature are kept constant the volume of the gas will vary inversely with the pressure it is exposed to. This law can be written by the formulas detailed below that are used by the algorithm of this calculator:
Boyle-Mariotte Law formula: P_{1}*V_{1}= P_{2}*V_{2}
Each of the variables in the equation can be determined if the other 3 variables are given:
- P_{1 }and P_{2} equations:
P_{1} = P_{2}*V_{2}/V_{1}
P_{2} = P_{1}*V_{1}/V_{2}
- V_{1 }and V_{2} formulas:
V_{1} = P_{2}*V_{2}/P_{1}
V_{2} = P_{1}*V_{1}/P_{2}
Where:
P_{1} is the initial pressure;
V_{1} is the initial volume;
P_{2} is the pressure changed;
V_{2} is the volume changed;
Assumption: Temperature (t) and Mass (m) stay constant.
